- Implemented lrintf(), lrint(), lroundf(), lround(), nearbyintf(),

nearbyint(), remquof(), remquo(), roundf(), round(), tgammaf(),
  tgamma(), truncf(), trunc(). Sort of implemented fmaf() and fma(),
  which really ought to be done in "SIMD" fashion.

  This completes the "real" floating point math library (ignoring
  for a moment that the floating point environment code is still
  not implemented).
